小脳血管芽細胞腫に後頭動脈椎骨動脈吻合，頸椎潜在性二分脊椎，前頭縫合遺残，甲状腺癌および赤血球増多症を合併した1症例について

A Case of Hemangioblastoma Associated with Spina Bifida Occulta, Persistent Metopic Suture, Thyroid Adenocarcinoma, Vertebro-Occipital Anastomosis and Erythrocytosis

Ⅰ．緒言

　一般に脳の血管芽細胞腫と他疾患との合併についての論文は数多く見られるが，われわれは頸椎のC₅，C₆における潜在性二分脊椎，前頭縫合遺残，甲状腺癌，後頭動脈椎骨動脈吻合，赤血球増多症を合併した血管芽細胞腫の1例を経験したので報告し，若干の考察を加えた．

We presented a case of hemangioblastoma associated with spina bifida occulta, persistent metopic suture, thyroid adenocarcinoma, vertebro-occipital anastomosis and erythrocytosis. We have not found a hemangioblastoma with these associations, as far as we have seen in the literature.

36-year-old male was admitted with complaints of nausea, vomiting and ataxic gait in June, 1970. On admission, the examination revealed no evidence of increased intracranial pressure except for elevated CSF pressure by lumber puncture and incoordination. The peripheral blood count disclosed slight erythrocythemia.
